Mars 3.is considered(consider) to be the most possible choice as its natural environment is less hostile than 4.that of other planets.So humans have been more and more interested in Martian 5.exploration (explore).Since the 1960s，we 6.have been sending (send) unmanned spacecraft to Mars，which send back valuable data and stunning images.Many space agencies are planning manned missions to Mars which could take place within the next 25 years.There is no doubt that humankind is drawn towards Mars.However，it is 7.a long way from the Earth to Mars.Besides，it is quite dangerous to travel through solar radiation.Therefore，8.sending(send) people to Mars requires all the skill，courage and intelligence of the human race. Right now，the Earth is getting warmer while 9.moving(move) to Mars is still a beautiful dream.Therefore，it is quite necessary for each of us 10.to take(take) better care of our Earth because it is the only one we have right now! Ⅰ.阅读理解 A (2024·黑龙江大庆实验中学月考)Space tourism is the term used to describe space travel for recreational or leisure purposes.What was once only a dream，as described in A Space Odyssey by Arthur C．Clarke，is now becoming a reality. Futurologists attempt to make predictions of what life will be like in the future.After the first man landed on the moon，they thought that hotels would be built on the moon by the year 2000.They also considered the possibility that，in the 21st century，families might go for a holiday on the moon.Neither of these predictions has come true yet—but the rapid development of technology may mean these predictions are possible in the years to come. Space Adventures is currently the only company to have succeeded in sending paying passengers into space.It worked with the Russian Federal Space Agency and Russia's rocket and space corporation Energia to provide flights for the world's first private space explorers.Each paid over $20 million for their 10-day trip to the International Space Station. Following successful explorations into space，other companies are now considering the possibility of enabling tourists to visit space.To make it affordable，suborbital(亚轨道的) space travel is being considered by some companies，like Virgin Galactic.Passengers would be transported to a height of between 100 and 160 km above earth，experience 3-6 minutes of weightlessness and a view of the stars before going back to earth.This is estimated to cost around $200，000 per person. While it could be an enriching experience，there are some terrifying disadvantages.Many critics say that a huge growth in the spaceflight industry could drastically speed up the process of global warming.The ozone layer(臭氧层) would be damaged further and the polar regions would suffer.In addition，space travel is only really affordable for the super-rich，though Virgin Galactic claims to be opening space to the rest of us. [语篇解读]　本文是一篇说明文。文章主要说明了太空旅行发展的可能性及其可能会带来的问题。 1．What do you know about space tourism? A．It is nothing but a dream. B．It's only in some fairy tales. C．It's a sightseeing tour in space. D．It's a scientific expedition. 解析　细节理解题。根据第一段第一句的内容(太空旅游是用来描述出于娱乐或休闲目的的太空旅行的术语)可知，太空旅行是一次太空观光之旅。故选C。 答案　C 2．What is paragraph 2 mainly about? A．The future life on the moon. B．Landing on the moon in 1969. C．Predictions about trips to the moon. D．The history of the moon exploration. 解析　段落大意题。文章第二段的主要内容是：未来学家试图预测未来的生活是什么样子。第一个人登上月球后，他们认为到2000年月球上会建旅馆。他们还考虑了21世纪在月球上进行家庭度假的可能性。这两种预测都还没有实现，但技术的快速发展可能意味着这些预测在未来几年内是可能的。由此可知，本段主要内容是关于到月球旅行的预测。故选C。 答案　C 3．Why is suborbital space travel considered possible? A．It's cheaper. B．It's safer. C．It's greener. D．It's more convenient. 解析　细节理解题。根据倒数第二段第一、二句的内容可知，随着太空探索的成功，其他公司如今正在考虑让游客参观太空的可能性；为了让人们负担得起，一些公司正在考虑进行亚轨道太空旅行。由此可知，一些公司考虑亚轨道太空旅行是因为费用更便宜，人们能负担得起，故选A。 答案　A 4．What is some critics' major concern about space tourism? A．Its safety. B．Its expense. C．Social equality. D．Environmental effect. 解析　推理判断题。根据最后一段第二、三句可知，许多批评家说，航天工业的巨大发展可能会大大加快全球变暖的进程；臭氧层将被进一步破坏，极地地区将受到影响。由此可知，航天工业的发展给环境带来很大的影响，这也正是批评家们对于太空旅行主要担心的问题，故选D。 答案　D B Sending human travelers to Mars would require scientists and engineers to overcome a range of technological and safety obstacles.One of them is the serious risk posed by particle (粒子) radiation from the sun，distant stars and galaxies. Answering two key questions would go a long way toward overcoming that difficulty: Would particle radiation pose a serious threat to human life throughout a round trip to Mars? And，could the very timing of a mission to Mars help shield astronauts and the spacecraft from the radiation? In a new article published in the journal Space Weather，an international team of space scientists，including researchers from University of California at Los Angeles(UCLA)，answers those two questions with a “no” and a “yes”．That is，humans should be able to safely travel to and from Mars，provided that the spacecraft has sufficient shielding and the round trip is shorter than approximately four years.And the timing of a human mission to Mars would indeed make a difference.The scientists determined that the best time for a flight to leave Earth would be when solar activity is at its peak，because，during this period，the most dangerous and energetic particles from distant galaxies are deflected (偏转) by the enhanced solar activity. A trip of that length would be imaginable.The average flight to Mars takes about nine months，so depending on the timing of launch and available fuel，it is reasonable that a human mission could reach the planet and return to Earth in less than two years，according to Yuri Shprits，a UCLA research geophysicist and co-author of the paper. “This study shows that while space radiation imposes (强加) strict limitations on how heavy the spacecraft can be and the timing of launch，and it presents technological difficulties for human missions to Mars，such a mission is possible，” said Shprits. [语篇解读]　本文是一篇说明文。文章主要介绍了前往火星的旅程中，人类将会受到太空中粒子辐射的影响。科学家认为，恰当的启程时间和合理的旅行周期将能确保宇航员的安全。 5．What's the function of the first paragraph? A．To list human's achievements in space. B．To show a possible way to travel to Mars. C．To introduce scientists' efforts to travel to Mars. D．To present one of the difficulties of the trip to Mars. 解析　推理判断题。根据第一段中的“One of them is the serious risk...distant stars and galaxies.”和第二段中的“Answering two key questions would go a long way toward overcoming that difficulty”可推知，第一段的作用是介绍人类前往火星需要克服的一个难题。故选D。 答案　D 6．What does the underlined word “shield” in paragraph 2 mean? A．Escape. B．Approach. C．Protect. D．Separate. 解析　词义猜测题。根据画线词后的“from the radiation”和语境可知，此处作者提出疑问：前往火星的恰当时机能否保护宇航员和宇宙飞船免受辐射的伤害？shield 意为“保护，保卫”，与protect意思相近。故选C。 shield...from...“保护……免受……”。 答案　C 7．How long can a round trip to Mars last considering the safety of astronauts and the spacecraft? A．Less than 4 years. B．Only 5 years. C．More than 6 years.　O．About 9 years. 解析　细节理解题。根据第三段中的“That is，humans should be able to safely travel...approximately four years.”可知，人类安全地往返火星是可行的，前提是宇宙飞船有足够的屏蔽物，而且往返时间少于四年。故选A。 答案　A 8．What can be the best title for the text? A．Will It Be Safe for Humans to Fly to Mars? B．Will Humans Travel to Mars in Two Years? C.The Timing of a Trip to Mars Is Planned D．Particle Radiation Changes for the Solar Activity 解析　标题判断题。通读全文，尤其是根据第二段内容和第三段中的“That is，humans should be able to safely trave...shorter than approximately four years.”可知，本文主要讲的是人类前往火星将会受到太空中的粒子辐射的影响。科学家认为恰当的启程时间和合理的旅行周期将能确保宇航员的安全，故A项“Will It Be Safe for Humans to Fly to Mars？”适合作为本文标题，故选A。 答案　A Ⅱ.完形填空 Viktor Usov has just been reunited with his cat Sasha after the cat was discovered wandering on the streets about 1，400 miles away from home.Usov said he had 1 let Sasha play outside one night five years ago，only to have him disappear.He once assumed the 2 result that he might have lost Sasha.
